Kirk Langstrom was a dedicated geneticist interested in extracting and isolating traits from one species and transferring them to another; however, he was so obsessed with his work he started to lose his wife and became a mockery of the field. He was hoping to use the enhanced hearing of bats to overcome his deafness. When he made a breakthrough he requested more funding but was denied. This struck him with overwhelming grief that made him lash out at his fiancée, Francine, and climaxed in him testing the experimental serum on himself. The serum succeeded and returned his hearing to him. He quickly makes amends with Francine, but Kirk's hearing has become superhuman and then it happens, he starts mutating into a man/bat hybrid. His mind is overcome by instincts and he is plagued by frequent blackouts. Kirk's transformation completes when he tries to commit suicide, and being complete for the first time, he flies away saving himself from death.

Alfred discovers him when he is attacked, luckily Batman was just coming home and managed to subdue the creature and bound it down. After examination, Batman discovers that this Man-Bat is in fact Kirk Langstrom. Batman returns Kirk to Francine and she reveals that, using Kirk's notes, she has formulated a possible cure. When Kirk awakens he escapes but Francine manages to inject the cure and Kirk reverts.

When he arrived there were murders being executed by a "Flying Man". When he managed to finally see Francine she denied him and his spirit was crushed. His last link to the human world was gone and now he was wanted for the "Flying Man Murders". Two vigilante cops managed to clip him when he was flying and he was knocked out. Killer Croc found him and brought him to the sewers and nursed him back to health. When he emerged he decided he needed to see Francine again even if she couldn't stand him. When he got there the real flying man was trying to kill Francine. It was revealed that Kirk and Francine were members of the "Secret Genetics Brotherhood". They were hoping to use Kirk and Francine's studies in genetic manipulation to make a human being without consciousness. They were horrified at the idea and left the brotherhood, but it turned out they stole their research and used it to make the monster that became the flying man.
